DRY CLOSET.

Application ed January l?. 1918.

To alf/whom t may concern:

ay citizen of the United States, residing atl lllestminster, in the county of Adams and State of Colorado, have invented certain new and useful improvements in Dry Closets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention embodies improvements in dry closets of the indoor chemical type, and especially relates to that class, which are readily attachable to and detachable from an air outlet conduit for ventilating purposes, which supplementally coperates with the action of a. suitable chemical or the like, preferably in liquid form, introduced into the container for relieving its contents of foul odors and other unsanitary cond'r tions.

The patented art, in this relation, having been sufficiently developed so that the general aims and advantages of these types of closets are fully understood, it will be unnecessary to further initially refer to' the objects of the present invention, which will be clearly apparent from the following description, though by way of emphasis it may be said that the invention is more peculiarly adapted for use on the farm, homestead, or other outlying localities, where the usual water ushing closets may not be feasibly installed, owing to lack of water facilities and sewerage systems.

With this general statement, the invention consists of the combination and structural arrangement of parts as hereinafter dis closed, the essential features of novelty being more particularly set forth in the ap pended claims; but to more clearly understand the same, reference will now be had to the accompanying drawings, in which like reference characters designate the same parts in the several views, of which- Figure 1, is an elevational view of the installed closet, the upper portion thereof and the lower portion of the vent pipe being shown partly broken away and in section; Fig. 2, is a. top plan View, looking down toward the line 2-2 of Fig. 1, a section being taken through the lower end of the vent pipe; Fig. 3, is a fragmentary View, showing the application of a pair of- Specication of Letters Patent.

eccentric binding clamps for the forward bottom of the apertured seat; Fig. 4, is a detail view of one of the split distending rings for the collapsible section of the vent conduit; Fig. 5, is a fragmentary cross-sectional view, taken on the line 5-5 of Fig. 4l; and Fig. 6, is a detail front view of a wall plate for securing the upper elbow of the vent pipe to a chimney flue or the like.

10 designates the metallic lower section of the vent conduit, which lower section is in the nature of a hollow pipe, closed at its bottom, and rigidly secured to a side wall of the room, or other suitable support, as by means of the fastening nails 11. rlfhis lower section of the vent conduit is positioned substantially above the licor, at a distance dependent upon the height of the container and its seat, hereinafter specifically referred to.

12 designates a metallic upper section of the vent pipe, which may be in the nature of an open ended hollow elbow, the lateral arm of which is adapted to snugly seat within a central aperture 13 of a wall plate 14, flatly secured to the wall of a chimney flue or the like by the nails 15, driven through diverging nail holes 16 in the wall plate let, the angular divergence of which nail holes causes the nails 15 to be held securely against displacement by a wedging action. The aperture 13 of the wall plate, of course, registers with the usual opening in the wall of the chimney flue.

Between the lower and upper metallic sections 10 and 12 is disposed an elongated tubular section 17, formed of an air tight, but freely flexible and collapsible cloth fabric or the like, such as canvas or duck, and the ends of which may be secured over the opposed open ends of the upper and lower metallic sections in any suitable way, shown in the drawings simply by wiring 18. This flexible intermediate tube is maintained open or distended by the spaced positioning of f resilient rings 19 interiorly of its length,

which rings may be in the nature of annular bands, split or divided as at 20, to permit of their ready insertion within the fabric tube before installation, and which are partly held in place by the outwardly punched pointed projections 21, with intermediate stitching 22, if desired.

The primary reason for making this in termediate section collapsible, isy that it Vcompassed by a flaring element 41.

avoids the necessity of connecting up a number of metallic sections, and enabling it to be knocked down and nested for packing the whole equipment in the container receptacle proper for shipment and storage, a matter of no mean importance in the saving of space andthe avoidance of misplacing and'oftentimes the loss of a part of the full equipment.

25 designates the closet proper or container, formed as a'plain receptacle, preferably of galvanized sheet iron or the like, which. may. be easily enameled for cleanliness and neatness vof appearance.

lIhe lower peripheral wall of this container receptacle may be apertured to provide 'for the attachment of an outlet pipe 26, controlled by a valve 27, which outlet connection may be coupled up with a drain pipe, through which the container may be emptied and flushed out as desired, although the simplicity of construction of the container 'enables it to be bodily removed for emptying7 by means of the usual bail 28.

' 0nv the top of the container is detachably mounted an internal downwardly deflecting marginal rim 29, provided with the central enlarged opening 30, over which is mounted the eat 31, having the usual opening 32, and which (may be of two-part construction, hinged as indicated at 33, said apertured seat being in turn provided with. a cover 34, hinged thereto as at 35.

The bottom, face of the seat 31, which at .its rear extends substantially beyond the container 25, is recessed, as at 36, to span the rear'wallof the container, providing a ventilating air passage around the rear top of the container, between the seat and the de :fle'ctor rim 29.

37 designates the wall of an air casing, provided at its top with a marginal fiange 38, secured in any suitable way, as by nails or screws, to the bottom of the seat 31, and

`having aI concave edge 39, struck on an arc -cess 36.,

This arrangement provides for an enlarged lVentilating chamber 40, communicating with the passage 36, and having its rear wall provided with an outlet aperture, en-

This latter receives and guides' in place the conically tapered end of a hollow connecting pipe 45, having its other end cut away at the top, as at 47, and projecting into the lower .sectionlO of thevent conduit through a circular opening 46. This end of the connecting ypipe 45 is provided on opposite sides with slotted alining arcs 48, riding over a connecting pinv 49, disposed transversely .wigthinthe section v10, thus coupling the connection with the vent pipe with a limited pivotal swing, so that the tapered end of the connecting pipe may readily seat itself, by means of the guiding flaring element 41, into airtight connection with thc outlet aperture of the chamber 40.

When so assembled, the closet seat may be more positively secured to the connecting pipe by means of a pivotal hook 43, engaging the pipe through a small aperture 44, which will hold the tapered end of the connecting pipe firmly seated. The seat 31 itself is in turn clamped at its forward portion to the depending flange of the detlector rim 29, by means of the eccentrically mounted clamp elements 42 (see Figs. 2 and 3) thereby drawing the edge 39 of the casing 37 snugly against the wall of the container, making the whole attachment quite air tight.

If desired, the rear portion of the hinged seat may be hooked at each side to the container base, to maintain the former in position, when the forward portion is unclamped and raised for urinal purposes. This has not been actually illustrated, as there is no view which would properly show the connection, but it is so obvious that the showing is not believed to be essential, no claim being made thereto. p

As in similar types of closets, I also employ a suitable chemical mixture in the con-v tainer, and the noxious odors and gases, not entirely thrown down or killed by the chemical action, are carried away, as indicated by the arrows, through the vent pipe by way of its coupling with the container. Also, while not essential, it is obvious that any of the well known means of forced draft, sometimes used in Ventilating systems generally, might be employed, if desired.

With the foregoing complete disclosure, it y is believed that a further detailed description of the operation would only be unneces sarily prolix, and while it will be understood that I do not make any broad claims to the detachable coupling up of a dry closet container to a vent pipe generally, at the same time, I do not limit myself to the exact details as set forth, excepting as come within the terms of the ensuing, as viewed in the light of the specification, contemplating a fair range of equivalents. v
